I've been trying to upload a couple of cabs I've used on Sprint without issue, and can't get them to load. Check out JD's or Mal's thread, or search in Mighty's, there's other cabs out there being used without any problems. Follow this link, there's two cabs there that I've used and don't have issues with them.
